FOR FORMING ROLL EDGES ON MATTRESSES.

Patented Jan. 2, 1912.

Serial No. 605,994.

To all whom it may concern:

Be it known that I, ARTHUR W. KINDEL, a States, residing at 1115 Cookstreet, Denver, in the county of Denver and State of Colorado,haveinvented certain new and useful Improvements in Apparatus for FormingRoll Edges on Mattresses, of which the following is a specification.

This invention relates to an apparatus for producing roll-edges onmattresses and its object resides in the provision of a device of simpleconstruction by the use ofwhich the method of forming roll-edgesdescribed in the application for patent Serial Number 605,995 filedsynchronously with the present one, may be carried into effect.

A11 embodiment of my invention is illustrated in the accompanyingdrawings in the various views of which like parts are similarlydesignated and in which- Figure 1 represents a perspective view of theapparatus, Fig. 2, a plan view of a portion of a mattress with thedevice in its operative position, and Figs. 3 and 4;, fragmentarycross-sectional views of the mattress showing the apparatus in two ofthe positions it occupies while the method of producing the roll-edge isbeing practiced.

Referring to the drawings by numerals, 2 designates two straight-edgedbars of wood which in the operation, constitute levers fulcrumed to turnabout longitudinal axes between and at opposite ends of two curved yokes3, with which they are pivotally connected by means of pins 3 insertedinto their respective ends. The bars 2 which, preferably, are taperedtoward their rectilinear edges 2' are each provided with a series oftransversely arranged, slender instruments 4, the sharp pointedextremities of which project beyond the said edges. The needles 1 oneach of the two bars alternate with the spaces between those on theother so that the instruments comprised in the two series may pass eachother when the bars are turned in about their pivotal axes. Each of thebars 2 is furthermore provided with an outwardly extending handle 5which facilitates their manipulation and increases this leverage.

In the operation of my invention, the oints of the two series of needlesconnected with the respective bars, into the cover 6 of a mattress 7along parallel lines at opposite sides of an edge 8 of 1 tion of thecover are inserted the same, in the manner shown in Fig. 3 of thedrawings. The bars 2 are then turned in opposite directions about theiraxes of rotation, between the yokes .3, until their faces are brought inengagement with the respective surfaces of the mattresses as illustratedin Fig. &. When the bars are in this position, they extend nearly in oneplane and by engagement of their straight edges 2? with the interposedportion of the mattress, oppose each others rotary movement and thushold the parts in position until released by movement of the bars abouttheir axes in the opposite directions. During the rotary movement of themembers 2 in the directions of the arrows in Fig. 3, a portion of thestufiing 9 of the mattress, is by means of the instruments 4;, forcedtoward the edge 8 of the same and the por- 7 engaged by the rectilinearedges 2 of the two barsare at the same time drawn together along thelines determined by the said edges. When the parts are thus temporarilysecured as shown in Fig. 1, the portions of the cover at opposite sidesof the edge 8, are fastened to gether along the line of contractiondetermined by the straight edges 2 of the bars 2, by stitching or sewingwith twine or other suitable material. The stufling which by themovement of the needles 1, was compressed in the portion of the coverbetween the edge 8 and the line of contraction, is thus permanentlyconfined therein and the roll-edge thus produced will, after theapparatus has been removed by rotating the levers in the oppositedirections, be firm, of uniform compactness and of equal width.

Having thus described my invention what I claim and desire to secure byLetters-Patent is 1. An apparatus for forming roll-edges on mattressescomprising in combination, two cooperative, rotatory members havingparallel edges constructed to draw and clamp the cover of a mattresstogether along lines at opposite sides of an edge thereof, and meanscarried by said members and projecting beyond the edges thereof tocompress the stuffing of the mattress within the portion of its coverbetween said lines and said edge during and by the rotary movement ofsaid members.

2. An apparatus for forming roll-edges on mattresses comprising a pairof cooperative bet-ween said ously rotated draw the said engaged leversmounted to rotate about parallel axes, and each having a straight edgeparallel to its axis of rotation, and series of slender a distancesuitable for the sewing required in the production of a roll edge.

3. An apparatus for forming roll edges on mattresses comprising twoyokes, cooperative members rotatable about parallel axes yokes, and eachhaving a straight edge parallel to its axis of rotation,

and series of slender pointed instruments carried by and projectingtransversely be yond the respective straight edges, the said leversbeing so disposed and proportioned that by engagement of their straightedges with the cover of a mattress at opposite sides of an edge thereofthey will when simultaneportions together to a distance suitable for thesewing 1 between said 'yokes, and each having a straight edge parallelto its axis of rotation, and series of slender instruments, pointedextremities of which project transversely beyond the respective straightedges, the said levers being so disposed and proportioned that byengagement of their straight edges with the cover of a mattress atopposite sides of an edge thereof they will when simultaneously rotateddraw the said engaged portions together to a distance suitable forsewing, and the said yokes being curved to admit the roll edge formed bythe contraction of said cover substantially as described.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
